Discovered by P.E. Lecoq de Boisbaudran in 1886 in Paris, France. Dysprosium is a silvery metal of the lanthanide group. It is relatively stable in air, reacts violently with water and dissolves in acids. Applications for this element are limited, but it is used as an alloying element to produce an alloy used for magnets, and as a poison in nuclear reactors where it stops the reaction from getting out of hand. The abundance in the Earth's crust of dysprosium is 6 ppm.

glass bead doped with 4% Dysprosium - NEW!

diameter ~ 13 mm - ~ 0.8 - 1 gram

Nice glass bead. Each one hand crafted. Under UV excitation the glass shows strong fluorescence with two strong peaks @ 485nm(blue) and 573nm (yellow)

Please do not use common UV LEDs, they produce wavelengths above 390 nm and are not suitable! Blacklight tubes work best! The UV lamp used for the photos has a wavelength of 365nm
